Disease epidemiology
Effectiveness evaluation
Primary scope : Effectiveness evaluation
12. Main objective(s)
What is the main objective of the study?
To compare all-cause in-hospital mortality in a group of ICU-admitted patients with complicated influenza who receive treatment with IVZ as part of their clinical care with all-cause in-hospital mortality in a propensity score matched group of ICU patients who did not receive this therapy during the same influenza season and/or pandemic(s).
Are there primary outcomes?Yes
The primary efficacy variable is defined as the length of time between the index date and all-cause in-hospital mortality. Patients who do not experience all-cause in-hospital mortality will be censored at 28 days post treatment/matching or at loss to follow up.
Are there secondary outcomes?Yes
- All-cause in-hospital mortality up to end of follow-up (defined as 28 days post index date or at loss to follow-up)
- All-cause in-hospital mortality at Day 7, 10 and 14 after treatment initiation/matching
- Ordinal scale for clinical course of influenza disease at Day 7, 10 and 14 after treatment initiation/matching
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Patients will be followed up for 28 days post index date
15. Data analysis plan
Please provide a brief summary of the analysis method
The primary analysis will consist of a matched cox regression model to estimate all-cause in-hospital mortality, presented as a hazard ratio for IV Zanamivir treatment vs matched control. A similar regression analysis will be performed to estimate in-hospital survival on day 7, 10 and 14 after treatment initiation/matching, and a proportional odds regression model will be fitted to analyse the ordinal scale date on the same days.
